  Improvements to the refining processes of cast iron,

  
The present invention relates. refining of cast iron

  
 <EMI ID = 1.1>

  
It has been well known for many years to practice refining cast iron by blowing industrially pure oxygen onto the surface of the cast iron bath, by means of a lance introduced into!

  
 <EMI ID = 2.1> <EMI ID = 3.1>

  
an inert gas under the surface of the metal bath, during the blowing of oxygen from above, in order to impart to the bath. a movement by which the efficiency of the oxygen blowing was increased. According to. -variants,

  
 <EMI ID = 4.1>

  
bottom of the converter.

  
In the following, the applicant has proposed to further improve

  
 <EMI ID = 5.1>

  
of a conventional lance: and an insufflation of oxygen from the bottom, with the intervention of a nozzle comprising two ccaxial conduits: The oxygen is then generally: blown through the central conduit, while the

  
 <EMI ID = 6.1>

  
pure surrounded by a protective agent on the other hand;, is essentially: characterized in that as a protective agent,

  
 <EMI ID = 7.1> According to the invention, the carbon dioxide surrounding the oxygen jet advantageously contains substances making it possible to improve the cleanliness of the steel obtained, for example substances

  
 <EMI ID = 8.1>

CLAIMS ^

  
 <EMI ID = 9.1>

  
weaver, into which is blown on the one hand at least, a jet of industrially pure oxygen above the level of the iron bath, and on the other

  
 <EMI ID = 10.1>

  
that as a protective agent, carbon dioxide is used.
